Lapho ukhetha i-aumshini wokushisela indawoekukhiqizeni izimoto, ukukhiqizwa kwebhethri, noma ukwenziwa kwensimbi, abathengi bavame ukubhekana nombuzo obalulekile: ingabe kufanele utshale imali kumishini yefrikhwensi ephezulu, emaphakathi, noma yendabuko ye-DC (imvamisa yamandla)?
Ubuchwepheshe ngabunye bunamandla kanye nemikhawulo yabo. Inketho efanele incike ezintweni zakho ezisetshenziswayo, umthamo wokukhiqiza, imigomo yokonga amandla, kanye{1}}nezinhlelo ezizenzakalelayo zesikhathi eside. Lo mhlahlandlela uchaza umehluko wobuchwepheshe, izici zokusebenza, kanye{3}}nezicelo zangempela zomhlaba zesistimu ngayinye ukukusiza wenze isinqumo sokuthenga unolwazi.
Ukuqonda Izimiso Zokusebenza
Ngaphambi kokuqhathanisa ukusebenza, kubalulekile ukuqonda ukuthi uhlobo ngalunye lomshini wokushisela amabala lukhiqiza futhi lulawula kanjani okwamanje.
Umshini Wokushisela Imvamisa Ephakeme
Amasistimu we-high frequency spot welding ngokuvamile asebenza ngaphezu kuka-10kHz. Amandla kagesi alungisa amandla angenayo e-AC, bese ewaguqulela ekubeni -imvamisa eshintshashintshayo yamanje nge-inverter. Lokhu{4}}imvamisa yamanje ephezulu idlula ku-compact transformer ngaphambi kokulethwa kuma-electrode.
Ngenxa yemvamisa yokusebenza ephezulu, impendulo yamanje ishesha kakhulu. Lokhu kuvumela ukulawula amandla okunembayo kanye nezikhathi zokushisela ezimfushane kakhulu. Amasistimu wokuvama okuphezulu avame ukusetshenziswa ezinhlelweni zokusebenza ezinembayo lapho ukushisa okuncane{2}}kudingeka izindawo ezithintekile.
Kodwa-ke, lezi zinhlelo zibandakanya amamojula we-elekthronikhi ayinkimbinkimbi kanye namamojula okulawula, okwandisa kokubili ukutshalwa kwezimali kokuqala kanye nezidingo zokunakekelwa.
Umshini Wokushisela we-Medium Frequency Spot Spot
Ukuze uqonde amathrendi embonini yamanje, udinga ukuqonda isimiso sokusebenza somshini wokushisela indawo yemvamisa emaphakathi.
Amasistimu amafrikhwensi amaphakathi asebenza cishe ku-1kHz. Baqale balungise-amandla okufakwayo ezigaba ezintathu, bese besebenzisa isiguquli ukuze baguqulele ku-middle frequency current. Lokhu kwamanje kudlula ku-medium frequency transformer futhi kuphinde kulungiswe ukuze kukhiqizwe ukuphuma kwe-DC okuzinzile kokushisela.
Uma kuqhathaniswa nezinhlelo zendabuko, ubuchwepheshe befrikhwensi ephakathi buhlinzeka ngokuphuma kwamanje okushelelayo kanye nokulawula okungcono kwe-waveform. Ukuqapha{1}}iluphu evaliwe ngokuqhubekayo kulungisa okwamanje phakathi nomjikelezo we-weld, ukuthuthukisa ukungaguquguquki nokunciphisa ukuhluka phakathi kokushisela.
Lesi ngesinye sezizathu ezinkulu ezenza ukuthi imishini yemvamisa emaphakathi ibe indinganiso yemboni ekukhiqizeni umzimba wezimoto.
I-DC (Power Frequency) Umshini Welding Wendawo
Imishini yokushisela indawo ye-DC evamile isebenza ku-50Hz noma imvamisa yomugqa ongu-60Hz. Basebenzisa ama-transformer amakhulu nama-rectifiers ukuletha i-DC welding current.
Idizayini yesistimu ilula futhi iyabiza{0}}. Kodwa-ke, ngenxa yemvamisa ephansi yokusebenza, i-transformer inkulu futhi impendulo yamanje ihamba kancane. Okukhiphayo kuzwela kakhulu ekuguquguqukeni kwegridi yamandla, okungase kuthinte ukungaguquguquki kokushisela.
Nakuba zisasetshenziswa kabanzi ekwenziweni okuvamile, lawa masistimu kancane kancane athathelwa indawo-ezindaweni zokukhiqiza ezisebenza kahle.
Ukuqhathanisa Ukusebenza
Ake sihlole ubuchwepheshe obuthathu ngokusekelwe ezintweni ezibaluleke kakhulu kubathengi.
Ukuzinza Kwamanje Nokuvumelana Kwe-Weld
- Amasistimu efrikhwensi emaphakathi ahlinzeka ngokukhiphayo okuzinze kakhulu ngoba asebenzisa-amandla ezigaba ezintathu kanye nokulawula kwe-inverter. Lokhu kubangela ukwakheka okungaguquki kwe-nugget kanye nekhwalithi yokushisela ephindaphindwayo, ebalulekile{2}}ekukhiqizweni kwevolumu ephezulu.
- Amasistimu amafrikhwensi aphezulu anikeza ukulawula okunembe ngokwedlulele, ikakhulukazi ezingxenyeni ezincane nemijikelezo ye-weld emifushane.
- Imishini yefrikhwensi yamandla e-DC ingase ibe nokuguquguquka okukhulu, ikakhulukazi ezikhungweni lapho ukuqina kwegridi kungahambisani.
Kubakhiqizi abagxile ekwehliseni izilinganiso zokukhubazeka, amasistimu amafrikhwensi amaphakathi ngokuvamile anikeza ibhalansi engcono kakhulu phakathi kokulawula nokwethembeka.
Ikhwalithi yokushisela nokulawula ukushisa
Ukulawula okokufaka ukushisa kubalulekile uma sishisela-insimbi enamandla, ishidi eliwuthayela, noma izingxenye zethusi.
- Imishini yokushisela indawo ye-Frequency emaphakathi ivumela ukulawula okungcono ukunqwabelana kokushisa, ukunciphisa isipatha kanye nokunciphisa ingozi yokusha{0}}ngokusebenzisa. Lokhu kuzenza zifaneleke kahle izakhiwo zezimoto kanye{2}}nezinhlelo zokusebenza ezihlobene nebhethri.
- Amasistimu amafrikhwensi aphezulu ahamba phambili ekushiseni-okuncane kanye nezinhlelo zokusebenza ezidinga ukulawula ukushisa okuqinile.
- Imishini ye-DC ingenza kahle ekusetshenzisweni kwe-carbon steel ejwayelekile kodwa ingase ibe nzima ngezinto ezithuthukisiwe.
Ukusebenza kahle kwamandla kanye nezindleko zokusebenza
Ukusetshenziswa kwamandla kuyisici esikhulu-ku-ROI yesikhathi eside.
- Amasistimu amafrikhwensi amaphakathi ngokuvamile athuthukisa isici samandla kanye nokusetshenziswa kwamandla ngo-15–30% uma kuqhathaniswa nemishini yokuvama kwamandla evamile. Eminyakeni embalwa yokusebenza, lokhu kuhumushela ekongeni ugesi okubalulekile.
- Imishini ye-DC ngokuvamile idla amandla amaningi ngenxa yokulahleka kwe-transformer nokusebenza kahle okuphansi.
- Amasistimu wefrikhwensi ephezulu ayasebenza kodwa angabandakanya ukutshalwa kwezimali kwangaphambili okuphezulu.

Uhlelo lokusebenza-Umhlahlandlela Wokukhetha Okususelwe
Ukukhetha umshini wokushisela indawo ofanele kuya ngezidingo zakho ezithile zokukhiqiza.
Ukukhiqiza Izimoto
Ukukhiqizwa kwezimoto kudinga amandla e-weld angashintshi kanye nokuphindaphinda. Amasistimu amafrikhwensi amaphakathi abusa le mboni ngoba aletha ikhwalithi eqinile ye-weld yamanje neqinile kuwo wonke amavolumu amakhulu okukhiqiza.
Ibhethri ne-Copper Busbar Welding
I-Copper ine-conductivity ephezulu kagesi kanye ne-thermal, okwenza kube nzima ukulawula okokufaka ukushisa. Imishini yefrikhwensi emaphakathi inikeza ukulawula okungcono ekwakhekeni kwe-nugget futhi inciphisa ubungozi bokushisa ngokweqile.
Ngokushisela okunembayo okukhethekile kakhulu, amasistimu amafrikhwensi aphezulu nawo angacatshangelwa.
Umshini Wasekhaya Nokwenziwa Kokukhanya
Ezingxenyeni ezijwayelekile ze-carbon steel ezinezidingo zokukhiqiza ezimaphakathi, imishini yokushisela indawo ye-DC ihlala iyisixazululo esisebenzayo-esisebenzayo.
Kodwa-ke, uma-okuzenzakalelayo kwesikhathi eside kanye nokusebenza kahle kwamandla kuyizinto eziza kuqala, amasistimu efrikhwensi emaphakathi anikeza ubufakazi obuqinile-bekusasa.
Ungawukhetha Kanjani Umshini Wokushisela Indawo Ofanele
Ngaphambi kokuthenga, cabanga ngalokhu okulandelayo:
- Yiziphi izinto zokwakha ozishiselayo? -Insimbi enamandla nethusi ngokuvamile idinga ukulawula kwamanje okungcono.
- Ithini ivolumu yakho yokukhiqiza? Imigqa{0}}ephezulu yevolumu iyazuza ekusebenzisaneni okuthuthukisiwe.
- Ingabe uhlela okuzenzakalelayo noma ukuhlanganiswa kwerobhothi?
- Kubaluleke kangakanani-ukonga amandla kwesikhathi eside?
Uma umgomo wakho uwukuthuthukisa ukuzinza kwe-weld, ukunciphisa amaphutha, nokwandisa ukusetshenziswa kwamandla, ubuchwepheshe befrikhwensi emaphakathi ngokuvamile buhlinzeka ngesixazululo esinokulinganisela kakhulu.
Isiphetho
Ubuchwepheshe ngabunye bufeza injongo. Amasistimu amafrikhwensi aphezulu alungele izinhlelo zokusebenza ezinembayo. Imishini yefrikhwensi yamandla kagesi e-DC ihlala iyonga ekwenzeni okuyisisekelo.
Kodwa-ke, kubakhiqizi abagxile kukhwalithi, ukusebenza kahle kwamandla, kanye ne-automation ekalayo, imishini yokushisela i-middle frequency spot imelela utshalomali olusebenzayo{0} lwesikhathi eside.
Ukukhetha imishini efanele akukhona nje kuphela ngentengo yokuqala. Imayelana nokuqondanisa ubuchwepheshe bakho bokushisela nesu lakho lokukhiqiza kanye nezinhlelo zokukhula zesikhathi esizayo.
